GravitationUnknown - 2009
Although gravity is the weakest of the fundamental forces, it is nevertheless the most universal-and the easiest to demonstrate! This program demystifies the properties and behavior of gravity with the help of real-world illustrations and animated graphics. Topics include the four fundamental forces or interactions; Newton's Law of Universal Gravitation; the physics involved in microgravity environments; the role played by gravity in the trajectories of space vehicles and satellites, including geostationary satellites; gravitational field strength and other planets; and the inverse square nature of the law of gravitation.
